Origin of brewer's yeast
Brewer's yeast is a dietary supplement widely used for its many health benefits. But where does this yeast come from and how is it obtained?
Brewer's yeast comes from the natural fermentation of the barley, malt and hops used in beer production. It consists of a species of fungus called Saccharomyces cerevisiae, which is also used in bread-making and wine-making. This fungus feeds on the sugar in the malt, producing carbon dioxide and alcohol. Brewer's yeast used as a food supplement is inactivated, i.e. it is heated and dried so that it can be consumed without risk. It is available in powder, capsule or tablet form.
